Application filed January at, 1528.

This invention relates to a device for purifying poisonous gases such ascarbon monoxide so that the same will be rendered non-injurious.

A further object is to provide a device in the form of an attachmentwhich can be placed in communication with the exhaust of 'an internalcombustion engine whereby the spent gases will be compelled to flow 1therethrough, the construction of the attachment being such thatchemical reaction will take place therein so that the toxic gases willbe changed before the gases issue from the attachment.

With the foregoing and other objects in View which will appear as thedescription proceeds the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed Without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In. said drawings,

Figure 1 is a side elevation of the attachment, the same being shownpositioned between the flared ends of opposed pipes.

Figure 2 is a'longitudinal section through the structure shown in Figure1.

. Figure 3 is an elevation of one of the heads of the attachment.

Figure 4 is a section on line 44 Figure 2.

Referring to the figures by characters of reference 1 designates acasing preferably cylindrical provided with an outwardly extendingannular flange 2 at each end thereof. Heads 3 preferably formed of sheetmetal, are seated upon the flanged ends of the casing and each head isprovided with a plurality of large openings 4 and other smaller openings5. A core 6 is fitted snugly within the casing 1 and is preferablyformed ofa mixture of asbestos and magnesite molded under pressure.- Inthis core are formed longitudinal passages 7 adapted to register withthe lar e openings 4 in the two heads and: ad i'tional small passages 8are provided in the core and are adapted to Serial No. 82,369.

register with certain of the openings 5. These passages 8 are designedto receive tie rods 9 the ends of which extend through the head, theserods being provided with nuts 10 or the like whereby the heads can bepressed tightly against the ends of the core and held properly assembledtherewith. Additional tie rods 11 are extended through the flanges 2 andthe openings 5 in the marginal portions of the head, these rods also Iserving to attach the heads to the flanges 12 provided at the large endsof flares 13 extending from pipes 14- By providing nuts 15 or the likeon the ends of the rods 11 the samecan be tightened so as to hold allofthe parts together securely.

Before the core 6 is placed in the casing 1 it is impregnated with amixture of barium dioxide, calcium chloride, potassium perfit?manganate, pyrogallic acid, bone ash and. ashes of nut shells and fruitpits. This mixture, with the magnesite, is commingled with the asbestos.

The ingredients mentioned can be combinedin any desired proportions forproducing the best results andthe said ingredients will have the qualityof combining with "arious toxic gases so that when the gaseous productsof combustion given off by an internal combustion engine are-directedinto this device, there will be no danger of poisoning by any of thegases as would be the case should they be discharged unchanged directlyinto the atmosphere.

It will be understood of course that the various parts can be of anypreferred sizes and configurations and that the device can be placed inany suitable position where it will receive the gases from an internalcombus- 90 tion engine before they can escape into the atmosphere.

What is claimed is:

1. The combination with a casing, apertured heads at the ends thereof,and means 05 for directing gases to one of the heads, of a core housedwithin the casing and abutting against the heads, said core havingpassages communicating with the apertures in the heads, and includingmeans for effecting a 0 chemicalchange in toxic gases entering'the core.

2. The combination with a casing, apertured heads thereon, and means fordirecting gases to one of the heads from the ex haust of an internalcombustion engine, of a.

5 core fitted Within the casing and against the head and havinglongitudinal passages communicating With the apertures, said coreincluding a mixture of asbestos, Inagnesi'te, and means for combiningchemically with toxic gases flowing into the passages. W In testimonythat I claim the foregoing as my own, I have hereto affixed mysignature.

JEAN A. CORNELIER.
